The slogan of Beijing's Olympic bid is "New Beijing, Great Olympics"

The main connotation is:

The modern Olympic Games, which has experienced a hundred years of vicissitudes, will be held in China, which has one fifth of the world's population, which will spread the Olympic spirit more widely and turn a new page in the Olympic movement. At the same time, the Olympic movement in the new century has also shown its unique charm to the people of the world with a brand-new look.

5. Between July and August

According to the bidding report of Beijing Olympic Games and some data, the temperature in the morning and evening of July and August is not too high.

Beijing has a temperate continental climate with four distinct seasons. The meteorological observation data of Beijing in recent years 10 show that the daily average temperature in Beijing is between 24.5℃ and 26. 1℃ from July 25th to August 60th. The highest temperature appears at 3 pm and lasts for a short time. Due to the large temperature difference between morning and evening in Beijing, the temperature is not very high in the morning and evening. The humidity in Beijing is suitable for outdoor activities.

Weather conditions have an important influence on sports competitions. For example, high temperature can easily make athletes tired and weaken their physical strength, while low temperature can make athletes' muscles tense and affect their performance. The influence of wind speed is more critical. For example, in the 100-meter race, long jump and other competitions, if the downwind speed exceeds 2 meters/second, only the name will be registered, regardless of the score (that is, the record created will not be recognized). Strong winds and heavy rains may even interrupt or reschedule the competition, which will affect the competition schedule and arrangement of the sports meeting.

It is most suitable to hold the Summer Olympic Games from the end of July to the beginning of August. However, the temperature in Beijing is relatively high during this period, and many people are worried that the athletes' competition status will be affected. However, from September to 10, the temperature is cool and there won't be too much high temperature.

Look at the temperature first. Although the average temperature in Beijing is as high as 25.7℃, the average maximum temperature in the afternoon is only 30. 1℃ due to the rainy season and the small temperature difference between day and night ... The maximum temperatures in Athens and Atlanta are as high as 32.4°C and 365438±0.7°C, respectively, due to the large temperature difference between dry days. That is to say, the temperature is much higher than that in Beijing during the daytime competition.

Look at the precipitation Thunderstorms, hailstorms, strong winds and other strong convective weather in midsummer in Beijing are indeed the most in the whole year, but the incidence is not high. For example, in the history of Beijing, the average number of hail days in July and August is only 0.2 days, and the average number of rainstorm days with daily rainfall exceeding 25 mm is only 2 to 3 days. Among them, the monthly average of rainstorm with daily rainfall exceeding 50 mm is only about 1 day. Moreover, because Beijing is located in the valley where Yanshan Mountain and Taihang Mountain meet, about half of these severe convective weather occurs at night when there is no competition.

Although the average relative humidity in summer in Beijing is as high as 80%, it is mainly high at night and in the early morning, and the lowest relative humidity is only about 60% in the afternoon, and the humidity generally does not exceed 70% during the daytime competition.

Throughout the four seasons in Beijing, although it is hot in midsummer, there is no cold in winter, no dust in spring, no strong wind to cool down in late autumn, and the temperature is relatively stable. Compared with previous Olympic Games, the climatic conditions in Beijing are most similar to those in Atlanta, but the temperature is slightly lower and the humidity is slightly higher. Of course, the sultry weather in Beijing at the end of July and the beginning of August this year is really not conducive to sports competitions, but the frequency of such weather is not high. It is not uncommon for a low-latitude city like Atlanta to have such sultry weather in summer. Besides, we have many modern cooling equipment and measures.
